Jongno-Gu. One day when I was four, my father's death notice arrived. My father, who claimed to come from an empire called Talochium and was the strongest paladin, left me behind. "If you wish, I'll send you back. To where you were born. To where you should have been. To where that man still lives." The last chance offered by the mysterious lifeform that appeared from my father's keepsake box. Now I can save him, right? But... The father from the past I finally reunited with seems a little off somehow. (Source: KakaoPage, translated)
